See CQRS/CONTEXT.md for conventions (stateless, no Context dependency, multistore tier model, typed exceptions).

1. Choose the base class

Create src/Adapter/{Domain}/{Domain}Repository.php. Choose the base class based on the multistore tier table in CONTEXT.md.

2. Core methods

Implement these methods (adapt naming to your domain):

• get{Domain}({Domain}Id $id): {LegacyObjectModel} — loads the ObjectModel, throws {Domain}NotFoundException if not found
• create(...): {Domain}Id — calls ObjectModel save() or add(), wraps in try/catch, returns new ID
• update(...) — calls ObjectModel save() or update()
• delete({Domain}Id $id) — deletes the entity, respects multistore if applicable

Reference: src/Adapter/Tax/CommandHandler/ uses a simple repository pattern, src/Adapter/Carrier/CommandHandler/ uses AbstractMultiShopObjectModelRepository

3. Multistore pattern (when using AbstractMultiShopObjectModelRepository)

• Receive ShopConstraint as a method parameter — never read it from Context
• Call $shopIds = $this->getShopIdsByConstraint($shopConstraint) at the start of every write
• Iterate $shopIds and apply the write for each shop context
• Modes: ShopConstraint::allShops(), ShopConstraint::shop($shopId), ShopConstraint::shopGroup($groupId)
• Single-shop installs still go through this path (returns array with one ID)

4. Sub-resource methods (if applicable)

For entities with has-many sub-resources, two strategies:

Atomic replace (simpler)

• set{SubResource}s({Domain}Id, array $items) — delete all existing rows, insert new set
• Wrap in transaction — partial replace corrupts data

Incremental update (cleaner)

• Compare existing rows with new collection, apply only changes
• Preferred when sub-resources have their own identity

Rules
